Platypus were found in fox scats (Brown 1990; Green 2003; Purcell 2008; Davis et al. 2015).

Studies not in support

No studies

Is the threat claim evidence-based?

There are no studies linking foxes to platypus populations.

Evidence linking Ornithorhynchus anatinus to foxes. Systematic review of evidence for an association between Ornithorhynchus anatinus and foxes. Positive studies are in support of the hypothesis that foxes contribute to the decline of Ornithorhynchus anatinus, negative studies are not in support. Predation studies include studies documenting hunting or scavenging; baiting studies are associations between poison baiting and threatened mammal abundance where information on predator abundance is not provided; population studies are associations between threatened mammal and predator abundance.
